Great Whites are emerging to change light as you know it.

A change in perception
The perception has always been that driving lights need to throw light as far down the road as they can in order to be of most benefit to the driver. In order to gain this sought after distance effectively, light is concentrated and contained to a single pencil beam, as a result sacrificing the spread of light.
The recent introduction of LED technology to driving lights, has brought with it, new observations. Effective Light is one such observation, and can simply be described as useful light.
A single beam of light focussed onto one spot 1km down the road may sound impressive, but in reality, there’s less effective light output for the crucial 300- 400m ahead of the vehicle.
An additional spread beam is often introduced to compensate for this lack of effective light.
Driving by candlelight
At one lux (the same brightness as a single candle) at 1km, the average person would struggle to identify anything at that distance. When you consider that even a fully loaded (64 tonne) B-Double at 100kph requires 127.1m breaking distance to pull up, it’s that immediate 300 – 400m that is most relevant for the driver. The kangaroo 1km down the road can hop away well before he is a hindrance to the driver, but the kangaroo 200m from the vehicle could easily hop onto the path of that vehicle, necessitating in the driver’s quick response to a potentially fatal obstacle.
The colour spectrum of LED is closer to that of sunlight which serves to help reduce eye strain. Great Whites spread a crisp light ahead of the vehicle, enabling excellent peripheral vision, which is important to detect pedestrians and other potential hazards. Research shows that peripheral vision and detection are enhanced under white light. This white light (as opposed to more yellow light produced by halogens) allows faster peripheral detection and therefore the opportunity for a faster reaction time from the driver.
Great Whites Driving Light Features:
- IP68 Rated - Waterproof up to 3metres
- Shock Proof and Vibration dampened rated up to 10G
- 50,000+ Hours* LED Life span
- 5 Year Warranty**
- Integrated Electronic Thermal Management (ETM) to regulate heat levels to prolong the life span of the LED by engaging PWM.
- Pulse Width Modulation (PWM) integrated circuitry flashes the LED faster than the human eye can see for reduced heat and prolonged LED life.
- Channelled Heat Sink designed for superior heat dissipation to prolong the life span of the LEDs.
- Polycarbonate Lens
- Extruded 6061 Aluminium Housing for ultimate durability and protection
- Includes environmentally sealed Deutsch connectors
- Can be mounted vertically, horizontally, diagonally or at any angle
- Latest LED Technology - Old technology requires the fitment of a separate spread and separate pencil beam light for output to provide both span and distance. Great Whites’ cutting-edge LED technology delivers both distance and spread of light in every individual LED. Gone are the days of mismatched driving lights.
